final rationale
Mean of 2 draws (0.94, 0.94). (0) Not yet resolved: Elections Alberta shows no Question 10 results; the vote is Oct 19 and official results are scheduled for Oct 29, inside the Jan 19, 2027 close. (a) Six days to the vote, about 16 days to official results. (b) Status quo: all public polls since May show Remain at or above 60% of all respondents; the latest are Léger 70/22 and Brown 72/23, about 75% of decided, and 338Canada averages about 76% Remain. The lowest, Angus Reid at 61/33, is still about 65% of decided, and the valid-votes rule excludes blanks and undecideds. (c) NO needs a roughly 15-point miss on decided share, driven by mobilized UCP and Option 2 turnout, leverage protest votes, federalist complacency or blank Q10 ballots; that would be historically unusual. (d) YES: Remain lands at 68–76% of valid votes, helped by record 80–85% turnout, Remain-leaning mail ballots and broad elite backing. Kalshi's 93% anchor and Polymarket's margin buckets (about 4% for Remain under 60%) agree, so I sit slightly above the Kalshi mid.

Planner reasoning
The Kalshi market price is the main anchor. Sibling threshold markets in the same series (other Remain-share cutoffs) together give an implied distribution for the Remain vote share. Polymarket may list the Alberta referendum as an independent crowd, the resolution source is Elections Alberta, and Wikipedia covers background on the referendum and the separatist movement. One targeted search looks for the most recent independence polls.

- current state: Every public poll since May puts Remain at 60% or above, and the most recent ones (Leger Oct 2–4 at 70%, Brown Sept at 72%) are at or above 70%. The risks are a late shift, differential turnout from a mobilized separatist vote, and the Angus Reid result at 61%, which is close to the line. The first official final results are expected only after the 48-hour hand count.
- base rate: All 27 public polls since May 2025 show Remain well ahead. Even the weakest recent one, Angus Reid in August, gives roughly 64% of decided voters (61/33), and most others imply 70–77%, so 60% clears by a wide polling margin. The main risks are differential turnout, "leverage" protest votes, the confusing question wording, and polling error. The official results (Oct 29) arrive well within the deadline.
- yes case: The strongest YES case is a 10-point cushion in the latest Leger poll (70/22), higher certainty and turnout among Remain voters, and a valid-votes denominator that drops undecideds. A repeat of the lowest-polling Angus Reid result would still land near 65%. Official results are scheduled for Oct 29, within the deadline.
- no case: The NO case rests on a polling miss of around 10 points. The most plausible routes are a mobilized UCP-heavy Option 2 turnout, "leverage" protest votes, and blank-ballot or denominator effects. Against that, every public poll is at or above 60% Remain, and turnout is forecast at a record 80–85%, which dilutes the hardcore-separatist advantage.

BOTTOM LINE: Every public poll since May puts Remain at 60% or above, and the most recent ones (Leger Oct 2–4 at 70%, Brown Sept at 72%) are at or above 70%. The risks are a late shift, differential turnout from a mobilized separatist vote, and the Angus Reid result at 61%, which is close to the line.

report: base rate
- [2026-10-11] 338Canada's referendum poll page (last updated Oct 11) lists 27 polls since May 2025. Every one has Remain ahead, from +25 to +60. The latest are Léger, Oct 3: Remain 70 / Leave 22 / undecided 7; Ipsos, Sep 20: 74/14/12; Janet Brown, Sep 15: 72/23/4; Abacus, Sep 6: 64/24/9; Research Co., Aug 25: 74/22/4; Angus Reid, Aug 12: 61/33/5. The page's summary shows roughly 76% Remain and 23% Leave, each ±6%, which looks like a polling average that excludes undecideds. https://338canada.com/alberta/polls-indy.htm
- [2026-10-08] Léger's own release (fieldwork Oct 2–4, n=1,001): Remain 70%, up from 65% in August. Reported likelihood of voting at 8–10 out of 10 rose to 77%. Remain voters are more certain than Leave voters (91% vs 71% rate their certainty at 8–10). https://leger360.com/alberta-referendum-october-2026/
- [2026-05-25] Angus Reid is the least favourable pollster for Remain. It had 60% No / 35% Yes on the exact official question in May, and 61/33 in August. Its simpler leave/stay wording gave 67% stay. Half of respondents called the question confusing. Rural Alberta was split 48-48. https://angusreid.org/alberta-referendum-question/
- [2026-09-25] The CBC/Janet Brown poll (Sep 8–21, n=1,200) used the exact ballot wording and found 72% Remain, 23% Leave. https://www.bloomberg.com/news/articles/2026-09-25/albertans-favor-staying-in-canada-weeks-before-separation-vote
- [2026-10-05] Hill Times: pollster Janet Brown says Leave support is "remarkably stable". Pundits warn that low federalist turnout or high Leave turnout could make the margin closer than polls suggest. About 658,000 special mail-in ballots were requested, which Duane Bratt expects to lean heavily Remain. https://www.hilltimes.com/2026/10/05/support-for-alberta-separation-remarkably-stable-and-low-federalist-turnout-could-make-final-referendum-outcome-closer-than-expected-say-political-players/520742/
- [2026-10-08] The Hub says polls show 20–25% for Leave and 65–70% for Remain. It cautions that Quebec 1995 and Brexit show polling error and turnout effects can matter. It also notes that some "leverage" voters may choose Option 2 without wanting separation. https://thehub.ca/2026/10/08/polls-suggest-separatists-will-lose-albertas-referendum-but-polling-history-is-full-of-surprises/
- [Historical reference class, dated 2021-10-26] Elections Alberta's last referendums, in October 2021, had official results announced Oct 26, eight days after the Oct 18 vote. The equalization question passed with 61.7% Yes. The daylight saving time question was 49.9% Yes / 50.1% No in the official release. Elections Alberta's results page shows 48.8% / 50.2%, which looks like a share of all electors rather than of valid ballots. That mismatch shows the "valid votes" denominator matters. https://www.elections.ab.ca/resources/media/news-releases/official-results-released/
- [2026-10-11] Elections Alberta says the unofficial count must be finished within 48 hours of polls closing. The Official Announcement of the Results is scheduled for Oct 29, 10:00 am. That is well before the Jan 19, 2027 trading close. https://www.elections.ab.ca/current-election-information/
- [2026-09-05] CBC reports Elections Alberta expects a full Question 10 count between 1 and 4 a.m. on Oct 20, with all unofficial results due by 8 p.m. on Oct 21. https://www.cbc.ca/news/canada/edmonton/alberta-october-referendum-plan-9.7331795
- [2026-09-25] Ipsos/Global News (n=600 Alberta residents, Sep 18–22): 70% Remain, a statistically insignificant drop from the late-May/early-June poll. The headline figure includes undecideds. https://globalnews.ca/news/12072083/alberta-referendum-ipsos-september-2026/
- [2026-10-09] Premier Smith says she will not hold a second separation referendum "as long as I'm premier" if Albertans vote to remain. The Question 10 result is non-binding under O.C. 160/2026. https://www.cbc.ca/news/canada/calgary/alberta-premier-danielle-smith-referendum-vote-9.7376571
- [Context] The Question 10 wording is a two-option choice, "remain" vs "commence legal process for a binding referendum". It is not a plain leave/stay question. Comparable pro-status-quo outcomes: Quebec 1995 No was 50.6%, though pre-vote polls were closer to even. Brexit Remain lost despite narrow poll leads. Here the polling gap is far larger, with the Remain share of decided voters (excluding undecideds) roughly 65–76% across pollsters. This comparison is from general knowledge and was not verified on a fetched page.
BOTTOM LINE: All 27 public polls since May 2025 show Remain well ahead. Even the weakest recent one, Angus Reid in August, gives roughly 64% of decided voters (61/33), and most others imply 70–77%, so 60% clears by a wide polling margin. The main risks are differential turnout, "leverage" protest votes, the confusing question wording, and polling error. The official results (Oct 29) arrive well within the deadline.
NOT FOUND: Any polling taken after Oct 4. Any betting or prediction-market odds from other venues. A track record for Alberta referendum polling specifically (the last Alberta referendum, in 2021, had no comparable polling data in my sources). Elections Alberta's convention for rounding to one or two decimals.
report: yes case
YES means: Remain (Option 1) gets at least 60.0% of valid votes on Question 10 in Elections Alberta's first official final results. Blank and rejected ballots are excluded from the denominator.
- [2026-10-07] The Leger fieldwork (Oct 2–4) gives the arithmetic behind the 70% headline. Remain 70 and Option 2 22 means about 76% of decided respondents. Remain would still clear 60% if Option 2 took nearly all of the 7% undecided (70 vs 29 is about 71%). The Remain lead is therefore about 10 points of cushion on the raw figure. Leger's own text says "a clear advantage" for Remain. https://documents.leger360.com/hubfs/%C3%89tudes%20M%C3%A9diatiques/%C3%89tudes%20M%C3%A9diatiques%20-%202026/10.%20October%202026/Media%20Release%20-%20Alberta%20Pulse%20Check%20-%20October%207,%202026.pdf
- [2026-10-07] Leger's turnout signal runs in Remain's favour. Likely voters (8–10 out of 10) rose from 68% to 77%, and the release says engagement is strongest among residents 55+ and NDP voters. Among Remain voters, 91% are highly certain, against 71% of Option 2 voters. The release reads this as a more firmly committed coalition. This counters the "mobilized separatists" risk. Same URL as above.
- [2026-10-07] Leger shows the UCP split is not a Remain collapse. NDP voters are virtually all Remain. UCP voters are "almost evenly split" between the two options. Remain's 60% needs only a modest share of the UCP base on top of the opposition. Same URL.
- [2026-10-11] Special-ballot returns are a Remain-leaning early bank. Elections Alberta had received just over 300,000 completed mail-in ballots by Friday, Oct 9. Mail-in ballots were requested by about 20% of electors. The Oct 5 Hill Times item had Duane Bratt expecting these to lean heavily Remain. Their share of a ~85% turnout is roughly 10–15% of ballots. https://www.cp24.com/news/canada/2026/10/11/elections-alberta-ready-to-deliver-as-advanced-referendum-polls-to-open-this-week/
- [2026-10-12] Elite and organizational mobilization for Remain is broad. Forever Canadian says it will run a get-out-the-vote drive to its 1.5 million-person list. Kenney and Notley are sharing a stage on Oct 13. Poilievre and Smith, both urging Remain, speak in Calgary on Friday. This undercuts the earlier UCP-voter lean toward Option 2 reported in the colleagues' reports. https://www.theglobeandmail.com/canada/alberta/article-alberta-referendum-campaigns-enter-final-push/
- [2026-10-12] Smith has said she will vote Remain. A "Stay in Canada, no to the nine" campaign (Stephen Carter) urges voters to reject the other nine questions. It says Albertans are "very likely" to reject separation. A conditional-Remain strategy aimed at Smith's critics widens the Remain coalition beyond federalists. https://www.theglobeandmail.com/canada/alberta/article-alberta-separation-referendum-nine-other-questions/
- [2026-10-26 precedent, fetched] Elections Alberta's official release for the 2021 referendums states percentages as share "of valid ballots cast", to one decimal. Blank ballots (49,401 on equalization) were excluded. Remain is therefore evaluated on decided votes. Polls' undecided/skip shares (4–9%) mostly drop out, and 60% is cleared more easily than the raw poll figures imply. The mismatch with the results-page wording noted by colleagues does not change the official release's denominator. https://www.elections.ab.ca/resources/media/news-releases/official-results-released/
- [2026-10-11] The timing is not a barrier to a YES. The Official Announcement of the Results is scheduled for Oct 29, 10:00 am, and the page says the count must be completed within 48 hours of close. The first official final results are therefore expected about 10 days after the vote, inside the Jan 19 close. https://www.elections.ab.ca/current-election-information/
- [Most likely YES path] Remain polls at 64–76% of decided voters in the recent polls the colleagues listed. The Angus Reid reading of 61/33 (about 65% of decided respondents) is the low outlier. Prerequisites for YES: (1) the Leger/Brown/Ipsos level of 70%+ holds, and Angus Reid's lower figure does not prove right; (2) turnout of 80–85% pulls in moderate and NDP voters as Leger's likely-voter data suggest; (3) UCP-leaning Option 2 "leverage" votes stay at or below roughly 30% of valid ballots. A result near 65–72% Remain would clear 60% with room for a roughly 5–10 point polling miss.
BOTTOM LINE: The strongest YES case is a 10-point cushion in the latest Leger poll (70/22), higher certainty and turnout among Remain voters, and a valid-votes denominator that drops undecideds. A repeat of the lowest-polling Angus Reid result would still land near 65%. Official results are scheduled for Oct 29, within the deadline.
NOT FOUND: Any poll fielded after Oct 4. Advance-vote turnout figures for Oct 13. Elections Alberta's 2026 rounding convention (the 2021 precedent is one decimal). Any breakdown of the mail-in ballots' Question 10 lean beyond Bratt's expectation.
report: no case
YES means: Remain (Option 1) gets at least 60% of valid votes on Question 10 in Elections Alberta's first official final results. The NO case is that it falls below 60%.
- [2026-10-11] Jason Kenney, a federalist advocate, said "the lower the turnout, the better for the separatist side". He added that at 40% turnout or below "they could actually win". He described Option 2 voters as hardcore separatists plus "frustrated federalists" sending a message. This is a mechanism the polls may not capture. Elections Alberta projects 80–85% turnout, which cuts against it. https://www.ctvnews.ca/canada/alberta-referendum/article/i-think-they-could-actually-win-low-turnout-could-favour-separatists-in-alberta-referendum-kenney-worries/
- [2026-10-01] The Brown/CBC poll breakdown shows 53% of UCP voters choosing Option 2 and 40% Remain. The same poll shows Option 2 at 25% in small centres and 28–30% across education groups. Nearly all NDP voters (98%) back Remain. Remain therefore depends on NDP and non-UCP voters turning out. Any UCP defections or a UCP-leaning turnout surge would hurt it. The poll's phone response rate was 11.3%. https://www.cbc.ca/news/canada/calgary/alberta-separation-janet-brown-danielle-smith-ucp-united-conservative-9.7364358
- [2026-10-08] Leger's October poll has UCP voters at 48% Option 2 and 43% Remain. The October CBC poll has them at 53/40. This is the largest bloc in Alberta. Its lean is the main path for Remain to fall under 60%. https://leger360.com/alberta-referendum-october-2026/
- [2026-10-06] Business Council of Alberta notes that people without a university degree are more than twice as likely to pick Option 2. It says polls may understate separatism if samples are unrepresentative. It also flags "leverage" voters and the Brexit pattern, where Leave voters showed up more than polls implied. Federalists may stay home if they assume the outcome isn't in doubt. https://businesscouncilab.com/insights-category/econminute/alberta-referendum-polls-2026/
- [2026-10-09] Federalist strategist Stephen Carter is shifting his campaign to "No to the nine" and says Remain is likely to win Q10. The separatist Alberta Prosperity Project is pushing "IGNORE THE 9, VOTE OPTION 2". This points to an asymmetry: federalist energy is being spread across the other nine questions, while separatist energy is focused on Q10. The Globe puts Option 2 at 20–25% through the campaign. https://www.theglobeandmail.com/canada/alberta/article-alberta-separation-referendum-nine-other-questions/
- [2026-10-11] 338Canada's own table has no pollster, even Angus Reid at 61/33, showing Remain below 60% of the whole sample. The Aug 12 Angus Reid poll was the closest to the line. Its Remain share of decided respondents was about 65%. A drift of roughly 5 points toward Option 2 among decideds would put Remain at the threshold. The latest tracked polls are mostly from Sept to early Oct. https://338canada.com/alberta/polls-indy.htm
- [2026-10-07] Mail-in problems: more than 3,000 special ballot packages came back invalid, and only about a third of the 652,000 mailed packages had been verified by Oct 7. Elections Alberta says the mail ballots are expected to lean Remain. Invalid mail ballots are excluded from valid votes, so any lost Remain-leaning mail ballots help the NO side slightly. The effect is small, and most affected electors were told to resubmit. https://www.theglobeandmail.com/canada/alberta/article-alberta-referendum-thousands-voters-invalid-mail-in-ballot-packs/
- [2026-09-29] Of the roughly 652,000 mail ballots sent, more than 131,000 were returned and validated by Sept 29. Late or unverified packages might not count. This adds some uncertainty about how many Remain-leaning mail votes end up in the tally. https://www.elections.ab.ca/resources/media/news-releases/referendum-information-updates-2/
- [2021-10-26] Technicality: the 2021 official release gave shares of valid ballots (equalization 61.7% Yes; daylight saving 49.9/50.1). The Elections Alberta results page in 2026 will be updated "following the release of Official Results". The 2021 page showed shares of electors (48.8/50.2) rather than valid ballots. Elections Alberta results pages use different denominators in different places. The market rule specifies valid votes. A reader who mistakenly used a share of all electors would see a lower Remain figure. https://www.elections.ab.ca/resources/media/news-releases/referendum-information-updates-2/ and https://www.elections.ab.ca/elections/referendum/referendum-results/
- [2021-10-18] Ballots are separate for each question and can be left blank. In 2021, 49,401 ballots were rejected as blank on equalization and 1,633 for other reasons. These ballots drop out of the valid-vote denominator. If federalists who are indifferent skip Q10, Remain's share could fall. Blank ballots are most likely among those who dislike both options. https://officialresults.elections.ab.ca/orResultsReferendum2021.cfm?EventId=68RQ1&QUESTIONNO=1
- [2026-10-09] Open Data Canada's explainer says Q10 has about 4% undecided. It says Leger is an online panel with no margin of error applicable. A 74% Remain figure appears in one poll. The 60% line sits about 10 points below the average poll result, so a NO outcome needs a material polling miss (my reading of the data). https://opendatacanada.ca/articles/alberta-referendum-ten-questions-explained
BOTTOM LINE: The NO case rests on a polling miss of around 10 points. The most plausible routes are a mobilized UCP-heavy Option 2 turnout, "leverage" protest votes, and blank-ballot or denominator effects. Against that, every public poll is at or above 60% Remain, and turnout is forecast at a record 80–85%, which dilutes the hardcore-separatist advantage.
NOT FOUND: Any poll fielded after Oct 4. Advance-vote turnout or composition data. Elections Alberta's rounding convention for the 2026 official results. Any evidence of an official-results delay beyond Oct 29. A track record of Alberta referendum polling accuracy.

(0) Not yet resolved: Elections Alberta shows no Question 10 results; the vote is Oct 19 and official results are scheduled for Oct 29, inside the Jan 19, 2027 close. (a) Six days to the vote, about 16 days to official results. (b) Status quo: all public polls since May show Remain at or above 60% of all respondents; the latest are Léger 70/22 and Brown 72/23, about 75% of decided, and 338Canada averages about 76% Remain. The lowest, Angus Reid at 61/33, is still about 65% of decided, and the valid-votes rule excludes blanks and undecideds. (c) NO needs a roughly 15-point miss on decided share, driven by mobilized UCP and Option 2 turnout, leverage protest votes, federalist complacency or blank Q10 ballots; that would be historically unusual. (d) YES: Remain lands at 68–76% of valid votes, helped by record 80–85% turnout, Remain-leaning mail ballots and broad elite backing. Kalshi's 93% anchor and Polymarket's margin buckets (about 4% for Remain under 60%) agree, so I sit slightly above the Kalshi mid.

(0) The condition is not yet met. The vote is October 19 and advance voting opened October 13. Elections Alberta shows no results; its official announcement is scheduled for October 29, well before the January 19, 2027 close.
(a) Six days remain until the vote, and about 16 days until the official final results.
(b) The status quo strongly favours Yes:
- Every public poll since May has Remain at 60% or more of all respondents.
- The latest are Léger (Oct 2–4) at 70/22, Janet Brown (Sep) at 72/23 and Ipsos at 74/14.
- On a valid-votes basis that is roughly 72–84% for these polls; the 338Canada average is about 76%.
- Even the weakest poll (Angus Reid 61/33) implies about 65% of decided voters.
- The 2021 precedent shows official releases report share of valid ballots to one decimal, which drops undecideds.
(c) No would require a polling miss of roughly 10–15 points on the decided share. Possible routes are a mobilized, UCP-heavy Option 2 turnout, "leverage" protest votes, confusion over the question wording, and federalist complacency or blank ballots. UCP voters lean toward Option 2 (48–53%), which is the main channel for this.
(d) Yes follows if record turnout (forecast 80–85%) dilutes the hardcore separatist vote. Remain voters are also more certain of their choice (91% vs 71%), and the 300k+ Remain-leaning mail ballots add to the bank. The likely result is Remain at 68–76%.
The Kalshi anchor is 93% (bid 92/ask 96). Polymarket margin buckets imply about 4–5% for Remain below 60%, an independent crowd that broadly agrees. Referendum polling misses of this size are rare, but not impossible given the fat tails. I'll stay near the market at 94%.
